STEPS-----------------------The issue can be reproduced at will with the following steps:

Installed the PDH PIP and configured the ODI and Webservices.

The ItemService wsdl and the ODI Webservices are up and running.

While testing the Item Webservice, I am getting the empty response.

Checked in the EGO_PUB_WS_FLAT_RECS table, but there is no record found in that table. I assume ODI stores the response in that table.

Also looking into the EGO_ITEM_DETAILS interface in ODI. There are some filters being used in the interface. Think that is restricting the data to the target flow. EGO_ODI_WS_ENTITIES --REF1_VALUE is also null, whereas in the filter its expecting a "Y".
